NetXMS Support Forum

Hi All,

I am new to the NetXMS as someone told me this tool is very cool!  Before, I have been using Nagios for many years.

I am trying to configure NetXMS to simple monitoring some common services based on TCP ports. So, I added the node to the NetXMS and tried to create "Network Service" under the node. I added HTTP, TELNET, ..etc but got this error in all the ports monitored.

Starting status poll on network service HTTP
Current service status is Unknown

My questions are :-

1) Is it a must to have agent installed in the node to be monitored in order to monitor the ports? In Nagios, we don't need to do that. Just defined the port to be monitored in Nagios server.

2) For the known services (HTTP, SMTP, SSH, POP3, TELNET), does we need to specify the "Request" and "Response" ?

I am running Windows 2008 R2 with MySQL server.

Any help is greatly appreciated!!!

many thanks!!

Hi!

Internally server uses it's own agent running on same machine to monitor network services. You should check that NetXMS agent is running on NetXMS server's machine, and that it has port checker subagent loaded - there must be

SubAgent = portcheck.nsm

entry in nxagentd.conf. You don't have to install NetXMS agents on monitored nodes to check network services.

Hi Victor,

I did include SubAgent = portcheck.nsm in the nxagentd.conf but I still got the error message

"Unable to check service due to agent or communication error"

I tried to run the agent with debug mode is on. It shows the portcheck.nsm loaded successfully and listens to 0.0.0.0:4700. However, when I manually poll the status of the device to be checked, there is no more log generated. The firewall in Windows 2008 R2 is disabled.

Any help is greatly appreciated!!

many thanks!!

Hi!

Check that you have 127.0.0.1 in MasterServers.
